In the Tuesday, December 10th Philadelphia Inquirer there was an article about this mural in South Philly.
It's located near 16th & Fitzwater Streets. Read the story here:

When I arrived in mid-afternoon, at first I did not like the the way the sun was lighting the mural on this cold wintery day.
As I approached it I felt the lighting really focused on this great man's face, his eyes, and showed his determination.
This giant of a man walked the earth during our lifetimes and this Philly-style tribute is beautiful as it sits on this narrow working class South Philly street.
